Effects of dark-adaptation time, irradiation time and nutrient level on F_v/F_m in Prorocentrum donghaiense (Dinophyceae) during different growth phases

Factors that affect maximum quantum yield values of photosystem II (Fv/Fm) during exponential and stationary phases were studied in Prorocentrum donghaiense at various dark-adaptation and culture irradiation times in three nutrient treatments. Dark-adaptation and culture-irradiation times were the main factors affecting changes in Fv/Fm during exponential growth. Fv/Fm in the three nutrient treatments generally decreased over time. Significant...
